A Fox News host has hit back at US President Donald Trump for criticizing the pro-Trump network.

Jedediah Bila, the weekend co-host of "Fox & Friends," attacked Trump on Twitter on Sunday for his criticism of the news channel’s top host, Chris Wallace.

"Enough with the 3rd grade name-calling. Chris is doing his job. The news should not be any president’s friend, ally, or buddy. If it bothered you when Obama complained about Fox News, but you’re silent on this complete nonsense, then just stop," Bila tweeted. "Seriously. Enough."

In one tweet earlier in the day, the US leader attacked Wallace, his father as well as Chuck Todd with the NBC News.

"Just watched Mike Wallace wannabe, Chris Wallace, on @FoxNews. I am now convinced that he is even worse than Sleepy Eyes Chuck Todd of Meet the Press(please!), or the people over at Deface the Nation. What the hell is happening to @FoxNews. It’s a whole new ballgame over there!" he wrote.

Bila made the comment as she was reportedly dealing with a COVID-19 infection.
